682-01-9 S16425 Tetra-n-propoxysilane silicon tetra-n-propoxide tetra-n-propyl ortho silicate tetra-n-propyl orthosilicate tetra-n-propyl silicate tetrapropoxysilane tetrapropyl orthosilicate CAS 682-01-9

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

682-01-9 S16425 Tetra-n-propoxysilane silicon tetra-n-propoxide tetra-n-propyl ortho silicate tetra-n-propyl orthosilicate tetra-n-propyl silicate tetrapropoxysilane tetrapropyl orthosilicate (CAS 682-01-9) is a high-purity analytical reference standard with the molecular formula C12H28O4Si and a molecular weight of 264.43 g/mol.

The molecular framework of 682-01-9 S16425 Tetra-n-propoxysilane silicon tetra-n-propoxide tetra-n-propyl ortho silicate tetra-n-propyl orthosilicate tetra-n-propyl silicate tetrapropoxysilane tetrapropyl orthosilicate (C12H28O4Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
